In some cases it s because the system is outdated.
Air conditioning second floor only.
Using separate central air conditioning units for each floor allows you to maintain a.
The second floor is often much warmer than the first so one area of the house often seems too hot or two cold.
However when the thermostat senses that the temperature on the main floor is the temperature your hvac system has been set for it will turn off the ac.
Reduce use of lights and appliances.
The hot air from the second floor rooms can be collected in the hallway and sent back to the air conditioner.

As air heats the density decreases.
The temperature differences are more pronounced the greater the height of the column of air.
You could turn the ac down even more.
Ductwork services second floor rooms through ceiling registers.
The challenge is to install adequately sized ductwork from the second floor hallway to the basement or furnace room.
Positioning a window air conditioner in those places will allow the unit to better regulate the heat on your second floor.
Hot air rises so the second floor is naturally going to be warmer.
Ducts run through closets on their way to first floor rooms.
Of course this means that your second floor has not yet sufficiently cooled.
If your house does not have this return air ducting on the second floor it frequently can be added.
You can even air seal your attic to prevent heat from seeping in.
Window ac units are quite affordable too.
The hot summer days and especially the nights bring back one of the most common home comfort problems.
To maintain balance a return duct allows air back into the fan and coil system and a filter placed inside the duct keeps the cooled air free of airborne dust and dirt.
Different temperatures on different floors of your home can signal an issue with how your air conditioning system works.
Central ac on second floor only.
The most common complaint regarding imbalanced temps and hvac units is that it cools the first floor but not the second floor.
Less dense air rises above colder more dense air.
Also adding an attic fan will help cool things down by circulating the air up there and decreasing the amount of hot air reaching your second floor.
We re thinking of putting central air in our house.
Ideally we d like a two zone system or two separate systems one located in the attic to serve the second floor and one in the basement to serve the first floor but we aren t sure if we can currently afford that.
Add extra insulation to your roof and attic.
Depending on the size you get you can spend as little as 150 or a good unit and less than 20 each month to run it every day.
